目的观察心脏再同步起搏(CRT)治疗慢性充血性心力衰竭(CHF)的临床疗效。方法选择心功能Ⅲ～Ⅳ级(NYHA分级)的患者12例,治疗前行心脏彩色多普勒检查及心电图检查,符合美国、中国心脏CRT指南的适应证,行CRT起搏器植入,术后第1周及第4周返院复查心脏彩色多普勒检查及心电图检查,观察CRT起搏器植入术前后患者心功能及病情变化。结果 CRT起搏器植入术治疗后12例患者心功能均明显改善,左室射血分数及左室充盈均增加,二尖瓣返流减少,NYHA心功能分级从Ⅲ～Ⅳ级提高到Ⅰ～Ⅱ级。结论心脏再同步起搏治疗慢性充血性心力衰竭近期疗效明显。
Objective To observe the clinical effect of cardiac resynchronization pacing (CRT) on chronic congestive heart failure (CHF). Methods Twelve patients with NYHA class Ⅲ to Ⅳ were enrolled in this study. Cardiac color Doppler and electrocardiogram were performed before the treatment. The results were in line with the indications of CRT guidelines in the United States and China. CRT pacemaker implantation, After the first week and the fourth week after the hospital review of color Doppler ultrasound examination and ECG, CRT pacemaker implantation before and after treatment of patients with cardiac function and disease changes. Results After CRT implantation, the cardiac function of 12 patients was significantly improved, left ventricular ejection fraction and left ventricular filling increased, and mitral regurgitation decreased. NYHA functional class increased from Ⅲ ~ Ⅳ to Ⅰ ~ Ⅱ level. Conclusions Cardiac resynchronization pacing is effective in the treatment of chronic congestive heart failure.
